Long-Range Hydrogen Gas Measurement via Raman and Rayleigh–Brillouin Backscattering

Hydrogen (H2) is a promising energy carrier, but its wide flammability range requires rapid and reliable leak detection. In this study, we developed a non-contact stand-off ultraviolet (UV) light detection and ranging (lidar) system that simultaneously acquires Raman and Rayleigh...
